Your brain, your values. Only you can know why you ascribe less value to things that AI readily produces, but it is fundamentally a choice you get to make.

In the beforetimes, a lot of people didn't value software, but many software developers still did.

You don't have to jump through hoops of your own making to justify the things you want to enjoy and, outside of the workplace, people won't value you as an individual based on any set of performance criteria.
